Since the measures of the two angles are in the ratio 8:1, this means the bigger angle's is 8x and the smaller angle is x. Since they are complementary, they add to 90°, so you create the equation 8x+x=90°. This can be simplified to 9x=90°. Then, you divide 90 by 9 to get 10. This means x=10. Next, you replace x with 10 to find the measure of the bigger angle. 8x10=80, so the larger angle is 80°.
The answer is D since is the only one that has the correct y intercept
This is a volume question. 8x8x8, 512 cubic inches of water.
The ratio of Nathan's nickels to dimes to quarters is 4 : 4 : 17.
<h3>What is the ratio ?</h3>
Ratio expresses the relationship between two or more numbers. It shows the number of times that one value is contained within other value(s).
- Number of dimes = 1/5 x 40 = 8
- Number of nickels = 1/5 x 40 = 8
- Number of quarters = 40 - 8 - 8 = 34
The ratio = 8 : 8 : 34 = 4 : 4 : 17
